SHOE-MACHINE.

To all whom it may concern Be it known that I, OnREnL Asrrron, a

citizen of the United States, residing at appeared for the last to rest,allowing the heel end Swampscott, in the county of Essex and State ofMassachusetts, have invented pertain Improvements in Shoe-Machines, ofwhich the following description, inconnection with the accompanyingdrawings, is a specification, like reference characters on the drawingsindicating like parts in the several figures. i

This invention relates to pulling-over and other machines for use in themanufacture of boots and shoes and has, for its object to improve themechanism by which a shoe is supported in such machines.

Inthe pulling-over machine in which the invention is shown as embodiedfor the purpose ofexplanation, said machine being illustrated and fullydescribedin United States Letters Patent No. 663,777 gran-ted December11, 1900, the shoe, containinga last, is

positioned wih its solevfaced upwardly against a bottom rest. It wasfound in prac" tice that the action of the upper pulling devices of themachine tends to displace the lastrearwardly in the machine during thepullingover operation andthe machine was equipped with a heel rest asexplained in United States Letters Patent No. 1,029,387, granted June11, 1912,, on an, application filed March 28, 1903. Inlthe furtherde:velopment of the machine forxwork not originally required of it,particularly in strongly pulling the upper lengthwise ,of the last andup over the toe, a tendency has fulcrum on the sole of the last todescend more or less and the toe end of the last to fail to resist thepull of the grippers. It is objectionable to employ in apullingovermachine theknown means, such as heel spindles, for holding upthe heel cndJof the last because of the additional time which would berequired to spindle the last and adjust it, and for other reasons.

In view of these considerations an important feature of this inventionconsists in an external heel end rest for a shoe having provision forsupporting the heel end of a shoe containing a last in inverted positionagainst downward displacement of the last. i The upward pull on theupper holds the shoe Specification of Letters Patent.

against the feet of the bottom rest securely enough to prevent bodilyforward movement of the last. i i i In the preferred embodiment, of thisinvention herein shown for exemplificationl have taken advantage of thisfact by formiingfthe heel rest to prevent downward move:

ment of the heel endof the, last without an accompanying forward bodilymovement, of the last. In the embodiment shown the oppositely inclinedheelend embracing faces of the heel rest have last supporting portionswhich are inclined forwardly at a sharp enough angle to extend under thelast or shoe and prevent downward displacementin the direction ofmovement aboutthe sole rest as a fulcrum; J i i i I i i Another featureof the invention consists in providing an external heelend rest withlast sustaining member which is adjustable in the direction 10f theheight, of the last, ThlSmhaS the advantage of affording pro visionforsustaining against depression lasts 1 of widely diifering thickness withtheir, soles in substantially the same plane. Herein the heel restcomprises a back plate upon which is carried members provided with heelenpcndicularly to that plane.

, These and other features of the invention w1ll now be described inconnectionwith apreferred embodiment of this invention and will then bepointed out in the claims. t

The pullingover machine is made substantially like that described in thePatent No. 663,777 before mentioned. fThis ma- ,80 gaging faceswhichareinclined forwardly at an acutewangle to the plane of the sole restand which are adjustable together perchine comprises grlppers whichseize the upper at the sides of stretch it about a shoe is held by meansof an external heel end rest against rearward displacement which mightbeefli'ected. tained by parallel arms the forepart and at the toe of theshoe and pull it upwardly to last that is presented in, invertedposition against a sole rest 2., The- This rest is sus- 4: which arefree} to swing laterally to position the heellrest downwarddisplacement.

transversely of the machine and also have a limited swinging movementbackwardly against the locking bar 5 for securing the rest intransversely adjusted position. These features of; construction are morefully described in the specification of the Patent- N 0. 1,029,387,before mentioned and their exact arrangement forms no part of thepresent invention. I

The forwardly extended portions of the arms at are connected to a backplate 10 which in the present example is V-shaped, the wings thereofbeing inclined forwardly and outwardly at similar angles to the 1nedianplane of the machine. The heel engaging member 12 of the heel rest isalso of similar V-shape in its general outline and is mounted on theback plate for vertical adjustment. -The illustrated provision for thisadjustmentcomprises gibs or clamping locks'la having lips on their rearsides between which and theengaging member 12 the edges of the backplate are clamped by screws 15. This mounting permits any desiredrelative vertical adjustment of'the members 10, 12. The upper portionsof the wings of "the member 12 are beveledas at 20 to provide facesadapted to extend under the rear end face of the inverted last andsupport the heel end of the last against The tendency to suchdisplacement results from the severe pulling by the toe gripper upwardlyof the last which tends to cause the last to fulcrum upon the sole rest2 and swing the heel end downwardly. The inclination of the faces 20 tothe plane of the last bottom or the plane ofthe sole rest is such thatthe last is prevented from swinging downwardly about the sole rest as afulcrum. In order that the last might swing-downwardly about saidfulcrum the shoe would have to be displaced forwardly, requiring it toslide along the inclines 20. Such forward displacement of the shoe isprevented by the frictional engagement of the usual toothed faces of thesole rest with the shoe bottom. It will be noted that the seat formed bythe faces 20 is adapted to embrace the cone portion of the rear endof'the last, said faces being for this purpose downwardly inclined bothinwardly and forwardly to provide sustaining means extending under thelast.

The member 12 is provided at the intersection of its diverging faceswith a vertical groove 22 to receive the usual tack which is partiallydriven into the heel end face of the shoe during theassemblingoperation.

The provision of this groove avoids engagement of this tack with theshoe engaging faces and thus prevents the in ury to the heel rest andsuch injury to the shoe as might result if the tack were bent over uponand jammed into the upper.

In the use of the invention the member 12 will-be adjusted in accordancewith the class of work to be done, whether mens, womens, or childrensshoes, into a vertical position where and where the diverging sides ofthe last, as the last becomes fuller toward the sole plate, will restupon and be sustained by the faces 20. The machine will then be used asdescribed in said prior patents.

Having explained the nature of this invention and described a preferredconstruction embodying the same I desire to eeur by Letters Patent ofthe United States protection for all of the patentable features andcombinations herein disclosed and the following claims are to beinterpreted and construed broadly in the light of this intention. Y
